🖹 Description
SA60-50-0,5 Electric meter
RESISTANCE SHUNT 100A 60mV , 0.5 CLASS
Current Shunt Resistor – ENTES SA60-100
What it is
A current measuring shunt resistor, specifically the SA60-100 by ENTES.
It is a precision device used to measure high DC currents by converting them into a small, proportional voltage signal.
Key specs
- 100 A → 60 mV
At 100 amps, it produces a 60 millivolt output signal.
This standardized output makes it compatible with most industrial measuring devices.
What it does
- Installed in series with a circuit
• Converts high current into a small voltage drop
• That voltage is read by:
o Panel meters
o PLC analog inputs
o Energy monitoring systems
This allows safe and accurate current measurement without exposing instruments to high current directly.
How it works
- Current flows through the shunt (metal bar)
• A very small voltage drop is created (Ohm’s Law)
• The measuring device reads the voltage
• The system calculates the current value
The resistance is extremely low, so it does not significantly affect the circuit.
Comparison (all three models)
| Model | Range | Sensitivity |
| SA60-30 | 0–30 A | High |
| SA60-50 | 0–50 A | Medium |
| SA60-100 (this) | 0–100 A | Lower |
Higher current rating = lower sensitivity, but higher capacity.
Where it’s used
- DC power systems
• Battery banks and UPS systems
• Solar / renewable energy systems
• Industrial control panels
• Energy monitoring applications
Practical rule
- Use 100A shunt → for large loads (prevents overheating)
• Use lower ratings (30A / 50A) → for better accuracy at lower currents
Choosing the correct shunt improves both measurement precision and system safety.
Important notes
- Must be installed in series with the load
• Uses separate measurement terminals (Kelvin connection) for accuracy
• Designed mainly for DC applications (not like AC current transformers)
Simple explanation
It’s a “sensor bar” for measuring current — this version is designed for higher current applications (up to 100A), converting it into a small voltage (60 mV) that instruments can safely read.
